Four years ago, the Occupational Safety and Health Administration (OSHA) partnered with six electrical contractors, one union and two industry organizations to create an unprecedented Electric Transmission and Distribution Safety Partnership focused on reducing worker injuries and fatalities. Today, the partnership's ability to drive change in an industry with deep-rooted traditions, work processes and methods is real.
One of the partnership's most tangible successes is the industrywide implementation of best practices — processes or methods that can be applied throughout the electrical industry to reduce the frequency of incidents. The partnership researched, identified, defined and implemented six initial best practices. The following summarizes certain best practices deployed and adopted by each partner company.
- Administrative Controls Best Practice
This practice was developed to eliminate injuries resulting from improper planning by ensuring key job hazards are identified and controlled. It states that the pre-planning process should begin at the pre-bid meeting and extend through the preliminary job site analysis. This best practice further states that the contractor request information from the host employer to enable adequate risk assessments prior to beginning operations.
- Job Briefing Best Practice
This practice provides a uniform methodology and outlines the key components of job briefings. During briefings, job sequence should be documented, hazards to be encountered should be identified, and steps should be taken to control or eliminate hazards by following certain processes. All crewmembers are to participate in a documented job briefing, to be held at the start of each work shift at the project site.
- Rubber Protective Equipment Best Practice
This practice establishes protocols concerning effective inspection. It states that prior to each use, all protective equipment be inspected for any damage, wear or contamination that would compromise its ability to insulate or isolate the linemen from different potentials.
- Qualified Observer Best Practice
This practice states that a crewmember be identified as an observer to ensure clearances are maintained and personal protective equipment and effective cover-up are installed. The observer shall be capable of identifying nominal voltages, energized components, minimum approach distances and proper safe work practices while crewmembers are working on energized lines.
- Insulate and Isolate Best Practice
This practice relating to insulate and isolate procedures states that a safety review, including assurances that company safety rules and proper cover-up procedures are in place, be followed and performed by a competent person.
- Cradle-to-Cradle Best Practice
This practice, which outlines protocols related to effective use of insulating rubber gloves and sleeves, states that rubber protective insulating sleeves and gloves be worn cradle-to-cradle when working on energized circuits or equipment from an aerial platform. Additionally, the insulating rubber sleeves shall meet or exceed the electrical class rating of the insulating rubber gloves when working on primary conductors.
These six practices are helping to make great strides toward improved safety for linemen.
